The truck is a 2006 GMC crewcab dually 4x4. It has the diesel with the Allison tranny and 40K miles. It's a tricked out setup called the Regency package. This is after market package approved by GM, I think it was only available for 2 years. It's got custom fiberglass running boards, a custom wood and leather interior with individual TV screens built into the back of both front seats (we'd never use these unless there was something special our Airedale wanted to watch) and an after market 50+ gallon fuel tank, special wheels and I think it has a class V hitch, not sure what else.
